(54) THE DEVICE FOR SYNCHRONIZATION TIME SCALE is connected to the receiver output, the second input of the latter is connected to the clock, the output of the selector is connected to the transmitter, at the second point - the shaper of auxiliary time syunnap and logic processing unit, the first input of which is connected to the output of the receiver, The second input is connected to the output of the auxiliary time signal generator, the output is connected to the input of the signal splitter, and the input of the auxiliary time signal generator is connected to the clock. The structural scheme of the prepa- racy is shown (“1st device; FIG. 2 and FIG. graphically show the time ratios of the main signals, moreover, FIG. 2 shows the temporal ratios of 1H-c, where V is the magnitude of the discrepancy of the clock scales, © is the delay of signal propagation from one point to another, and FIG. 3 shows the ratios at, -T / d. The output of clock 1 is connected via the auxiliary time signal generator 2 to the input of the transmitter 3. At the first point, the output of receiver 4 is connected to one of the inputs of the signal selector 5, to the BTOpOKiy input clock 6 is connected; Output of the signal selector 5 is connected to the input of transmitter 7; At the second point, the output of receiver 8 is connected to one of the inputs of logic processing unit 9, the second input of which is connected to the output of the auxiliary time signal generator 2, and the output is connected to signal separator 1O . One output of the signal splitter 10 is connected via a time converter of Intervals 11 to the time interval meter 12, and the second one is connected to the second input of the time interval meter.12. The second input-time converter 11 is connected to the clock 1 output. The device operates as follows. The clock signal 1 is fed to the auxiliary signal generator, the output of which receives three pulses, the first coincides with the clock 1 signal, the second is separated from it by the value of T, and the third - by 3 t from the first. These signals are transmitted to transmitter 3 and transmitted to the first point, where they are received by receiver 4, from whose output they are fed to one of the inputs of signal selector 5, and to the other input of selector, the signal comes from clock 6, which is separated from V1; in pshppgu discrepancy shkal hours. When, where 0 is the time of the distribution of sig} e1pa from one point to another, the device is as follows. From the transmitter output, the clock signals of the first and second points with the auxiliary time signals are retransmitted to the second point and received by the receiver. Then, these signals are sent to one of the inputs of the logical processing unit, which separates the signal of the second pu clock from the clock signal of the first item. Then they go to the signal splitter 10, from one output of which the clock signal of the first point enters the input of the time interval meter 12, and from another output the clock signal of the second point relayed by the first point goes to time converter 11, which converts the time interval between the signal hours of the second point and the second point relayed from the first point of the clock of the second point in such a time interval that it is equal to 0. This signal and the signal received from the first point al chysov fed to measuring time intervals, which determines velichinuU. When V-in, the device works as follows. The clock signal of the second point with the auxiliary time signals is received by the receiver 4 at the first point and fed to one of the inputs of the signal selector 5, to the other input the clock signal of the first point is given. The output signal of the signal selector 5 is retransmitted to the first point, where the logic processing unit 9 allows to establish the coincidence of the clock signal of the first point and the retransmitted clock signal of the second point due to the fact that the second point, its input, receives the clock signal of the second point with auxiliary time signals. Further, the device works in the same way as in the previous case. Thus, the proposed device makes it possible to increase the likelihood of eliminating measurement ambiguity by eliminating the previously required preliminary scale step of a 17: -1 scale while increasing the informative reliability of scale synchronization.
